Abstract

En radiomottageranordning har en hovedmottager (10) og en multippelmottager (12). Hovedmottageren og multippel-mottageren er koblet sammen ved hjelp av en demperlogikk (34) som er i stand til å avgi et dempesignal til den ene eller annen mottager i den hensikt å redusere vedkommende mottagers følsomhet. Mottagerfølsomheten reduseres for å hindre et forholdsvis sterkt, mottatt signal fra å frembringe ringing I (dvs. vedvarende oscillering) i mottagerfilteret.
